Van Houweling, 41, rode 209 metres further than the previous mark of 46.065km, established in 2003 by Dutch rider Leontien Zijlaard-van Moorsel in Mexico City.
The California based rider already held the women’s US Hour Record (45.637km), which she set last February, also in Aguascalientes. In addition, she is a five-time UCI Amateur Road World Champion, most recently winning the road race and time trial titles at the 2014 UCI World Cycling Tour Final in Ljubljana, Slovenia.
"You never know if everything is going to come together on race day, Van Houweling said. "Everyday this week I was thinking, ‘Am I going to be 100 percent? Does my knee hurt? Am I getting the sniffles? Is it too hot? Or too cold?’
"I feel fortunate that everything came together today and that I felt in control. I am relieved that everything came together and thankful for everyone that helped me make this happen."
